There is provided a method of coating a substrate comprising at least one secondary amine, by contacting the substrate surface with a compound comprising at least one carbon-carbon double bond, wherein an electron withdrawing group is on at least one side of the carbon-carbon double bond, so that a complex is formed between nitrogen in the secondary amine and the carbon-carbon double bond. Then areaction is initiated to form a covalent bond by reaction of nitrogen in the secondary amine and the carbon-carbon double bond, by subjecting at least a part of the formed complexes to actinic radiation, wherein the wavelength of the actinic radiation is adapted to be absorbed by the complex.When a further top- coat is added, the resulting surface has a high hardness, and the scratch resistance isimproved. 提供了一种通过使基材表面与包含至少一个碳-碳双键的化合物接触来涂覆包含至少一种仲胺的基材的方法，其中吸电子基团处于所述碳-碳双键的至少一侧上，使得在所述仲胺中的氮与所述碳-碳双键之间形成络合物。然后，通过使所形成的络合物的至少一部分经受光化辐射而引发反应，通过所述仲胺中的氮与所述碳-碳双键的反应以形成共价键，其中所述光化辐射的波长适于被所述络合物吸收。当添加另外的面涂料时，所得表面具有高硬度，并且耐刮擦性得到改善。
